I think the point is not being made here. It's not that I do not have
alternatives, but I have the following hardware:
Dell 2950 with 6 1TB drives.
I want to configure it as a single RAID 10. Why Raid 10? Because that gives
the best of a combination of performance with a three disk stripe, and the
redundancy of mirroring.
Yes, I could build it as three RAID 1's, and stripe them in LVM, but I would
take a performance hit for that.
The issue is that within a very short time we are going to have 2TB disks, and
does that mean that at some point we will be forced to boot from < 2TB drives
only ?
GPT labeled disks take care of this issue. Grub2 lets you boot properly from
GPT labeled drive, or patch current grub and initrd. SLES does not support
GPT nor grub2.
Novell should be able to easily support this configuration, it's not that
exotic.
